Specification of Letters Patent.

Patented J une 5, 1908;

Original application filed August 27, 1901, Serial No. 73,460. Dividedand this application tiled August 1, 1905. Serial No, 272370t .'lU 1MMw/wm it may concorre;

Be it known that I, EDWARD B. Hass, a citizen of the United States,residing in the borough of Brooklyn, city of New -York, State of NewYork, have invented certain newr and useful Improvements in Writing-Machines,A of which the following is a specification.

In my Patent No. 700,687, dated Mey V20, 1902, application for which wasfiled Apr-i126, 15101, l have shown and claimed a structure containinglexible type-bar-actuating conv nections hatfingthegeneral constructionand mode of operation of those herein disclosed. That patent shows andclaims, however, de tails of .construction not herein disclosedV and Ytowhich the claims thereof are drawn, the

right being reserved therein to make generic claims in my application,Serial No. f of which this case is a division.

"he construction herein disclosed is speciic land subordinate to genericclaims made in my application filed August 1, 1905, Serial No. 272,171,which is also a division of my a plicaton, Serial No. 73,460. 1 Nodetachab e adj ustable fixed pieces or anchor-points (hereinafterdescribed) in an organization of the general character herein shown areclaimed in my application Serial No. 73,460.

The accompanying drawing is a vertical longitudinal section showing somuch of a machne'as is deemedA desirable to illustrate the invention. o'Y The drawing shows a ronteetroke t e-bar writing-machine. It iscontemplate that each typebar shall have two characters thereon and thateither the type-.bar segment or 'platen shall be shifted to print atwill either upper or lower case letters. As shown, provision 'is madefor shifting the-platen.

The frame is of any appro riate construc tion. At a suitable ont be owthe plane in which the platen is coated is mounted the type-bar segment1 in which the type-bars 2 are pivoted on a ro Y or wire, as usual. Theylie toward the machinaagainst asegmentai rest. To the heel or projectionof each typebar is attached the rear end of a exingconnection, the frontend of which is secared te a ixed 4point or lpiece 4, adjustably anddetachablymounte nection in a` se ent 5 located toward the front of themac ine and in front of the trans- 'sistance and type-bar velocity darinby YAa" slotendsset-screw een;

verse plane in which` the heads of the type-V `applied to the type-bars,and springs may be applied to the key-levers. I a universal bar 12 beempio ed beneath the key-levers, it may, as nena be urged up'st'ardly aeinst the key irlevers by spring pressure. ithe or both arran ements maybe employed. It is suflcent t at the spring reaction wherever andhowever applied shall properly assist in l returning the type-bars totheir position of rest, and so normally maintain them.

To secure a uniform depth of depression ci the har-pieces, the points ofconnection of the li 6 with the type-bars or the angle at which thelinks 7 are disposed may be rtaried. When c. nger-piece and its key aredepressed, link 13 is drawn down, flexing the connection downward andswi g that part of it in front of the point of exure-a e., link -emundits point of connection with the fixed piece thus drawing the rear link6 toward the front of the machine and actuating the type-bar by a pnli.This movement is characterized by a mmirnumo resistance at 'the startwith correspondingly-'low velocity of the type-bar and an increase in1E- t e complete downward excursion of the gerpiece.

Two key-levers only are shown. 9x is the center key of .the upper row,connected with the central ile connection running to the lowest point oft e segment 5. 9Y is one of the end keys of thehjont row and isconnected with a flexing connection running to the end ofthe segment. Y

The construction of the carri e and platen and 'mechanism for shitng theatter may be of any appropriate character. 'As shown, the carriagetravels upon rails 29 and 30, mounted in brackets located at the sidesof the frame. The platen 31 isrnounted in a frame IDO 32, carried in theends of parallel pivoted arms riage. The lower arms 34 are fast to theends of a rock-shaft 35, from the center of which projects an arm 36whose end is acted upon by a cross-rod 37, held in the ends ofbell-crank levers 38, located at the sides of the machine and fast to arock-shaft 39. The bell-crank 38 at the left-hand side of the machinehas connected to it a link 40 to be suitlbly actuated on the depressionof a shiftlhe relation of the type-bars and flexing connections is muchthe same, affording substantial uniformity of behavior. The structure islight, cheap, and simple and affords a marked refinement of touch of thefingerpieces. Obviously when the device or connection for operating theflexing .type-baractuatingl connection is applied at the hingejoint of te latter tensile strain only is exerted upon the parts thereof from thepoint of flexure to the opposite ends, respectivel and such parts maytherefore be very lig t and inexpensive and preferably are made of wire.Preferably the joints between the members of the flexing connection andbetween it and the iixedoint and type-bar are such as to allow slig ttwisting movements. This is particularl desirable at the type-bars nearthe ends o the segment.

The arrangement designated by me a fiex- 1n connection may have in someforms the ful operation of a reverse or accelerating toggle and in allformsI is of the nature of such a toggle. As illustrated, application ofpower thereto is in a line lintersecting one drawn between the fixedpoixit and the point of attachment to the type-bar.
